High-performance fluid and gas transfer solutions for automotive applications. Engineered for durability, featuring power steering hoses, A/C lines, brake hoses, water hoses, and exhaust pipes.
Automotive hoses and piping are the fluid, gas, and exhaust transfer lines that keep a modern vehicle running — from power steering and air conditioning to braking, cooling, fuel delivery, and exhaust. This guide covers every major hose family, material construction, OEM standards, and platform coverage to help you source the right line for any vehicle program or aftermarket application.
An automotive hose is a reinforced elastomeric or metallic line engineered to transfer fluid, gas, refrigerant, or exhaust within a vehicle's systems. Unlike industrial hydraulic hoses, automotive hoses must be lightweight, low-permeation, and qualified to vehicle-specific OEM specs (Honda HES, Toyota TSC, GM GMW, Ford WSS-M, VW TL), while surviving -40°C to +150°C under-hood temperatures, constant vibration, ozone exposure, and 10+ year service life.
Dafluid manufactures the full automotive hose portfolio for passenger cars, light trucks, commercial vehicles, and off-highway equipment — covering power steering, A/C refrigerant, hydraulic brake, radiator/heater coolant, fuel, and exhaust systems — all under IATF 16949 quality system with full PPAP and IMDS submission support.
Our catalog covers every hose family used across modern vehicle systems:
High-pressure (twin steel braid) and low-pressure (textile braid) lines for hydraulic steering systems. SAE J188 / J189 / J2050 compliant. Pre-crimped OE assemblies for Honda, Toyota, GM, Ford, Nissan, BMW.
Barrier hoses for R134a, R1234yf, and R744 (CO₂) refrigerants. HNBR / nylon barrier construction. Suction, discharge, and liquid lines for HVAC systems.
DOT-compliant brake hoses (FMVSS 106) and rigid brake lines. EPDM / SBR rubber with textile braid. Compatible with DOT 3, 4, 5.1, and silicone DOT 5 fluids.
EPDM hose with textile reinforcement for engine coolant, heater, and degas circuits. Rated 125–135°C continuous, 150°C peak. Available in molded and straight lengths.
Fluorocarbon (FKM) or HNBR barrier hose for gasoline, diesel, ethanol (E85), and biofuel. SAE 30R9 / 30R10 / 30R12 low-permeation. EVAP and PCV lines available.
Stainless steel 409 / 304 / 316 exhaust tubing, with interlock and flex sections. Mandrel-bent for optimal gas flow. Catalytic converter and DPF-compatible.
